WlNDMlLL-MOTOR.

SPECIFICATION forming part of Letters Patent 1\ To. 252,737, datedJanuary 24, 1882.

Application filed October 15, 1881. (No model.)

To all whom it may concern:

Be it known that L'BLANCHARD CHAMBER.- LAIN, a citizen of the UnitedStates, residing at Bellefontaine,in the county ofLogan and State ofOhio, have invented a new and useul Improvement in Windmill-Motors, ofwhich the following is a specification.

My improved device is adapted to be clipped to the vertical pitman orreciprocating rod of a windmill, and to convert the reciprocating motionthereof into continuous rotary motion, while entirely avoidingdead-centers. For this purpose I employ an oscillating yoke having rackson its oppgsite sides and pivoted at top to the clip which isconveniently fixed to the pump-rod, a pair of pivoted arms being used inconnection with the oscillating rack-yokes for guiding the same in itsvertical movement and placing its respective racks into gear with theopposite sides of the driving-pinion alternately as said racks arecarried up and down.

In order that my invention may be fully understood, it will be explainedwith reference to the accompanying drawings, in which- Figure l is anelevation of a windmill with the invention applied. Fig. 2 is a faceview of the guides and pinion on a larger scale. Fig. 3 is a perspectiveview of the rackyoke detached. Fig. 4 is a plan or top view of the clipand stud by which the rack yoke is attached to the pump-rod.

A may represent a wind-Wheel of any form or construction mounted on asuitable tower or standard, B, and having on the rear extremity of itsshaft (3 a crank-wheel, D, which runs a reciprocating rod, E, incustomary manner.

A suitable pump is shown at 'F.

G is the oscillatiugrack-yoke of my improved motor. It is provided oneach side with an inwardly-projecting set of cogs or teeth, g g, and atbottom with three studs, h z'j.

k is an aperture at top of the yoke by which it is suspended from astud, l, projecting from the face of the clip L, the arms m m of whichreceive a clip-plate, N, and nuts '02, by which the device is securelyfastened to the pump-rod E. The stud Z has an aperturenear its extremityfor the reception of the split key 0, to retain the oscillatingrack-yoke upon it.

P is a plate or standard forming one partof the stationary frame of mymotor. In the said frame are bearings for the pinion-shaft Q, on whichare a pinion, R, and a fly-Wheel, S.

T T are a pair of guiding-arms, pivoted on studs 15 1., respectively,and pressed inward toward the center by springs U U, the inward movementof said arms being arrested by studs 1; v, the-first of which may benear the heel of the arm, while the stud c is in position to receive thecontact of the upper end of the arm T, which is thrown against it.

WV represents a central guide consisting of a vertical rib projectingfrom the face of the plate P.

a; is a stud a little on one side of the lower end of the guiding-rib W.

The oscillating yoke is confined to its proper plane of movement by astrap, Y,bolted atits ends to the face of the plate P.

In order to prevent noise, rubber cu'shionsz are placed on the studs 0;,c, and a, and cushions z on the faces of the arms T T where they come incontact with the respective studs.

The operation is as follows: Supposing the parts to be in the positionshown in Fig. 1, the pump-rodis now ready to make its upward stroke. Atthis time the pressure of the guiding-arm T on the stud it throws thebottom of the pivoted yoke'to the right, by which means the rack g onthe left side is placed in position to gear with the left side of thepinion It and rotate the shaft and fiy-wheel in the direction indicatedby the arrow. This upward stroke, bringing the right-hand studj incontact with the guiding-arm T, moves the same to the right, while thepressure thereof holds the central stud,i, in close contact with theright hand side of the vertical guiding-rib W until the said stud,reaching the top of said rib, is arrested by the upper fixed stud, o,projecting from the plate P. At the same time thepressure exerted by thespring of thcpivoted guide-arm T throwsthe yoke to theleft, bearing therighthand studj of the yoke against the side of the ICO right side ofthe pinion It, and continue the rotation of the shaft and fly-wheel inthe same direction as indicated by the arrow. During the downward strokethe left-hand stud h presses the left-hand spring-arm T sidewise in themanner already described with reference to the right-hand arm until thecentral stud, i, reaches the bottom of the vertical guiding-rib W, whenit is thrown sidewise until arrested by the bottom stud, a:, when theupper stroke is performed as before, a continuous rotary motion beingthus imparted to the shaft.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In combination with the vertical reciprocating rod, the vibratingraok-yoke G, pivoted thereto, and the pivoted guide-arms T 1", pressedinward by springs UU, theguide-arms being intermediate of the springsand rack- 20 yoke, substantially as and for the purposes set forth.

2. The combination, with the vertically-reciprocating rod and thevibrating rack-yoke, of the detachable clip L for pivotingthevibratingrack-yoke to the vertical reciprocating rod, substantiallyas and for the purposes set forth.

3. The rack-yoke G, formed with cogs g g and studs h ij, as set forth.

4. The combination of the vibrating rackyoke, bearing-plate P, pivotedguide-arms T T, springs U U, central guiding-rib, W, and studs 0, o, andor, substantially as and for the purposes set forth.
